Letzte Kontakte synchronisieren

Also, hier mal zwei Artikel die ich dazu von IBM bekommen habe. Der Test der praktischen Umsetzung, ob das so funktioniert wie beschrieben, läuft. So ein Feature, noch ein bißchen besser konfigurierbar, hat Notes auf jeden Fall gebraucht! :)

Nummer 1:

Abstract

--- Zitat ---You have recent contacts synchronization enabled.By default,next recent contacts sync
executes after a period of 1 week.How can you set the recent contacts sync to execute after
every 30 minutes or an hour?

Content

--- Zitat ---You can set the next and subsequent execution of the recent contacts sync by setting the following parameter in client Notes.ini file:


NABEntriesSyncInterval=<Interval in minutes>

e.g. NABEntriesSyncInterval=30

where interval in minutes is 30.

Abstract

--- Zitat ---Notes 8.0.0 -> 8.5.0 Standard clients using recent contacts feature can cause Domino server slowdowns during synchronization of recent contacts with the Domino server.

Content

--- Zitat ---Notes 8.0.x -> 8.5.0 Standard clients using recent contacts feature can cause Domino server slowdowns due to overly frequent DPAB synchronization.  Basic clients do not cause this issue.  Standard clients rolled out with recent contacts disabled, do not cause this issue.  With peak load and certain client versions outlined above, the server can become unresponsive for an extended period of time.

How do I know I am running into this? Unresponsive servers and if you take an NSD, you see the stack referenced at the bottom of this document.

Tactical Client Solution: If you are currently experiencing Domino slowdown issues that match the stacks below then read on.
A tactical solution is to push out a notes.ini parameter to your Notes Standard 8.0->8.5 clients as follows to minimize impact (Notes.ini parameters can be pushed out via administrative policy).   
These INIs will delay the DPAB sync to occur every 7 days, which is the default in 8.5.1 and above:

- Notes 8.0 and 8.0.1 standard clients: NABEntriesSyncInterval=10080 (This represents 7 days in minutes.).
- Notes 8.0.2 and 8.5 standard clients: Set NABEntriesSyncInterval=10080 and NABEntriesSyncInitial=10080*
- Notes 8.5.1/8.5.2 standard clients: No Action, they already default to 7 day synchronization

*NABEntriesSyncInitial=10080* will effectively prevent the DPAB Sync operation from occurring on 8.0.2 and 8.5 until 7 days have elapsed while the client remains up and running.

 It is best to stagger pushing out the INI so that all your users are not synchronizing on the same 7 day cycle.  i.e. Push INI to 20% of users on Monday, 20% on Tuesday, etc to spread load throughout week.

This tactical solution will delay DPAB synchronization against a Domino server for 7 days for most clients with the exception of 8.0 and 8.0.1 startup and does not require a code change.
This tactical solution will delay DPAB synchronization against a Domino server for 7 days for most clients with the exception of 8.0 and 8.0.1 startup and does not require a code change.  This delay has the effect of spreading this activity more evenly through out the week.

Early Tactical Domino Solution: If you are currently experiencing Domino slowdown issues that match the stacks below then read on, if a customer is unable to push out a Notes.ini parameter to relevant client versions or finds the server impacted even with the 7 day DPAB synchronization, we have a Domino Hot Fix today that disables client Synchronization.  The client will attempt to synchronize, but will not since the Domino server will stop it.  This will mean, the following information will stop:
1.   Update of phone number data in Recent Contacts.     
2.   Renames: DPAB would stop reconciling renames.  Example: if I were renamed to Samantha Darrin from Sam Darrin, and had the server fix on,  Samantha Darrin  would start showing up as a secondary option in the typeahead dialogue.  But after a period of time (Domino setting)  I'd get an undeliverable mail message if I chose Sam instead of Samantha.   
3.   Certain use cases involving internet certificates (B to B S/MIME activity) expiring would trigger.

4.    DPAB's primary "type ahead" capability remains when the Domino hotfix is installed.   New recipients are added in FIFO (First In, First Out) order.   The hotfix disables the updating of Recent Contacts.


Background
The Notes Standard Client has a feature called recent contacts that is on by default.  This feature stores recent names in your DPAB (Dynamic Personal Address Book).  Periodically, these names are synchronized by looking up against the Domino server.  This operation can be taxing.  In 8.5.1 the default behavior of the client has been changed to only sync every 7 days.  Here are the behaviors for various releases for DPAB synching:
- 8.0 and 8.0.1 does the DPAB sync once every 24 hours and on client startup.  These versions also allowed you to delay the sync with NABEntriesSyncInterval=x (in minutes) but it did not effect client startup operation, so DPAB sync would occur on each client startup.

- 8.0.2 and 8.5 does the DPAB sync once every 24 hours and 1 hour after client startup.  Introduced the INI parameter NABEntriesSyncInitial=x (in minutes) to tweak initial sync after startup.

- 8.5.1 does the DPAB sync every 7 days and this value persists even across client restarts. So on client restart, if 7 days has elapsed since last sync, the sync will occur, but will be delayed for 1 hour.


Note: DPAB Synchronization should should not be confused with the "Synchronize Contacts" feature that replicates contact information between your DPAB and your mail file.  There is no UI choice to enabled/disable DPAB Synchronization.  It occurs by default if you have entries in the recent contacts view in your DPAB.
